Demon for Hire

Black Shadow Detective Agency

Jonathan Mercer
Crime & Fantasy Fiction Critic

A Thrilling Noir-Fantasy Fusion

Count S. A. Olson masterfully blends the gritty, hardboiled detective aesthetic with supernatural elements in Black Shadow Detective Agency: Demon for Hire. The novel is a page-turner, capturing the classic noir atmosphere with a protagonist who feels as if he stepped out of a 1940s crime novel—except he’s also a half-daemon. The dialogue is sharp, witty, and immersive, perfectly suiting the novel’s pacing. The character dynamics, particularly between Jason Black and his familiar, Shadow, add both humor and depth. However, the descriptive prose can sometimes be overly dense, slowing down the momentum. The plot keeps readers engaged with its mix of mystery and supernatural intrigue, making this book a must-read for fans of urban fantasy and noir alike.

A Demon PI You’ll Love to Follow

Olson’s protagonist, Jason Black, is everything a noir detective should be—sharp-witted, jaded, and compelling. But what sets Demon for Hire apart is its seamless integration of supernatural elements into a traditional detective story. The world-building is rich, with magickal entities coexisting alongside 21st-century urban settings, lending a fresh spin to the genre. Pacing is well-managed, though the opening exposition feels a bit heavy-handed. The novel’s strength lies in its character relationships, particularly Black’s interactions with clients and supernatural foes. While the romance subplot remains subtle, it adds emotional weight. Fans of Jim Butcher’s Dresden Files will feel right at home.
